Answer:
d. It is best measured using the statistic variance inflation factor (VIF).
Explanation:
Multicollinearity is an important issue in multiple regression model, having many independent/ explanatory variables. Multicollinearity is the situation in which two or more independent variables are highly correlated. It is problematic because it increases the standard error of independent variable coefficient & undermines its statistical significance
Variance Inflation Factor [VIF] is a check & corrective measure of multicollinearity.
- VIF as a multicollinearity check : It quantifies the correlation between one explanatory variable with other explanatory variables.VIF = 1 implies there is no multicollinearity (correlation between independent variables); VIF upto 5 implies there is moderate multicollinearity (correlation between independent variables). VIF > 5 implies high multicollinearity (correlation between independent variables)
- VIF as a multicollinearity correction : Calculating
= σ^2 / ![[TSS j (1 - R^2j)]](https://tex.z-dn.net/?f=%5BTSS%20j%20%281%20-%20R%5E2j%29%5D)
; where TSS = total sum of square of variable j , σ^2 = j variance, R^2 j = R^2 from regressing all other independent variable on variable j

Answer:
Since the real rate of interest is negative, this means that the purchasing power of the savings have decreased over the year.
Explanation:
Data provided:
Interest rates = 7.85 %
The rate of inflation = 12.3 %
Now,
The Real interest rate is calculated as :
Real interest rate = Nominal interest rate - Inflation rate
on substituting the respective values, we get
Real interest rate = 7.85% - 12.3%
Or
The real interest rate = - 4.45%
Here,
Since the real rate of interest is negative, this means that the purchasing power of the savings have decreased over the year.
Answer:
(2). Although her request to telecommute was denied, Lindsay will begin a flextime schedule in two weeks.
Explanation:
The second choice would be the most preferred as it conveys the idea in a formal and precise manner. <u>The complex sentence beginning with the subordinate clause already hints the listener that the key message is yet to come. It helps him/her in understanding the intended message without any confusion</u>. The first sentence fails to create that specificity as it connects two independent ideas which remove the listener's focus from the main idea i.e. 'she will begin a flextime schedule in two weeks.' Thus, option (2) adopts the correct format and sentence structure to deliver the message effectively, efficiently, and precisely.
